QLD: Wallumbilla Gladstone Pipeline

The Wallumbilla Gladstone Pipeline (WGP – formerly known as the Queensland Curtis LNG Pipeline/QCLNG Pipeline) is a transmission pipeline that operates across central Queensland. The pipeline is owned and operated by the APA Group. 

The WGP is 540 km in length and 1050 mm in width, and has a capacity of 1588 TJ/day.

The WGP connects gas fields in Queensland's Surat Basin and the APA Group’s East Coast Grid to the Queensland Curtis LNG (QCLNG) export facility on Curtis Island near Gladstone. The pipeline has interconnections with the Australia Pacific LNG (APLNG) and Gladstone LNG transmission pipelines.

The WGP is currently a non-scheme pipeline, and is subject to the access regime for non-scheme pipelines under Chapter 6A of the NGL and Part 23 of the NGR. In 2010, the Commonwealth Minister (being the relevant minister) granted a 15 year non-coverage determination for the QCLNG Pipeline.

Construction of the WGP was completed in 2014. The QCLNG was owned by QGC until 2015, when the pipeline was sold to the APA Group.
